This cool, refreshing homemade Strawberry Lemonade is the perfect way to beat the heat on a warm day. This easy sugar-free strawberry lemonade recipe uses only a few simple ingredients: freshly squeezed lemons, pureed strawberries, water, and Splenda. Feel free to use your favorite zero-calorie, sugar-free sweetener, or spike it for a fun poolside drink!

Lemonade is a warm-weather staple. Making a healthier, refined-sugar-free version is a great way to drink more water throughout the day and stay hydrated. Not to mention, super tasty, so you’re inclined to drink more. If you’re throwing a party, serve it with a bottle of vodka for spiking. 😉
Ingredients you’ll need
- Organic strawberries (you can also use fresh blackberries and raspberries), rinsed and stems removed
- Large lemons
- Filtered water
- Granulated Splenda (or Whole Earth brand sweetener)
- Ice
How To Make Sugar-Free Strawberry Lemonade

Step 1: Make the lemonade base. Juice the lemons and pour into a 2-quart pitcher. Add two cups of water and the Splenda. Stir until the Splenda is dissolved.
Step 2: Blend the strawberries. Place the strawberries, the remaining cup of water and ice into a blender and blend until smooth.
Step 3: Combine and serve. Add the lemonade to the strawberry mixture, stir and serve.
Helpful Tips
- Frozen strawberries work too. If fresh strawberries aren’t in season, swap in frozen (thawed slightly) and blend the same way. You may need a touch less water since frozen berries release more liquid.
- Adjust the sweetness to taste. Start with the recommended amount of Splenda, then add more a tablespoon at a time. Sweetness needs can vary depending on how tart your lemons are.
- Make it fizzy. Swap the water in the blender step for sparkling water for a lightly carbonated version.
- Batch it for a crowd. This recipe scales up easily; just keep the ratio of lemon juice to strawberry puree to water the same.
- Strain for a smoother texture. If you don’t love strawberry pulp in your lemonade, pour the blended strawberry mixture through a fine-mesh strainer before combining it with the lemon juice. However, I don’t find this step to be necessary.

Storing
Keep leftover lemonade in an airtight pitcher or mason jars in the fridge. It’ll keep well for 4 to 5 days. Give it a stir or shake before serving since the strawberry puree can settle at the bottom.
Want to freeze it? Pour into a freezer-safe container, leaving an inch of headspace, and freeze for up to 3 months. Thaw in the fridge overnight and stir well before serving. You can also freeze leftover lemonade in ice cube trays and use the cubes to chill future batches without watering them down.
FAQ
It stays fresh for 4 to 5 days when stored in an airtight container in the refrigerator.
Fresh-squeezed is recommended for the best flavor, but bottled lemon juice works in a pinch. You’ll need about the same amount, roughly 1.25 cups of juice from 6 large lemons.
Granulated Splenda or Whole Earth (erythritol and monk fruit blend) both dissolve well in cold liquid. Liquid stevia also works if you prefer to skip granulated sweeteners; just start with much less since it’s more concentrated. We personally prefer the flavor of Splenda to other sweeteners.
Yes, using a zero-calorie sweetener like Splenda, Whole Earth, or stevia keeps this low-carb and keto-friendly. Strawberries are naturally low in sugar compared to most fruit. There are 4 grams of natural fruit sugar in this recipe from the berries.
Yes, it holds up well in the fridge for a few days, so it’s an easy make-ahead drink for gatherings. Just give it a stir before serving.
Raspberries or blackberries both work well in place of strawberries, or try a mix of all three.

It should stay fresh for several days in the fridge. It would be fine to drink up to a week, just stir well before serving.
How long wil this last in the fridge? Sounds yummy!!!
Thank you so much Marsha! I hope you enjoy it! 🙂
This looks soooo tasty Amee – pinning to make soon! YUUMMMM!
You know Ashley, I’d have to agree with that and I would just add a bit and keep tasting it until you get it just right. I love NuNaturals liquid stevia and I’ll try it with that next time I make a batch. 🙂
I think liquid stevia tastes a lot better. I wonder how much you would use.
